Oligoquantization in low-rate lossy source coding

The theory of high rate lossy source coding is well developed both with respect to the practice of quantization and its fundamental rate distortion limits. But many modern compression systems for natural signals such as audio and images operate at lower ra ...

The JPEG 2000 still image compression standard

Touradj Ebrahimi

With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this need in the specific area of still image encoding, a new standard is currently being developed, the JPEC2000. It is n ...

On source/channel codes of finite block length

Martin Vetterli, Michael Christoph Gastpar, Bixio Rimoldi

For certain fortunate choices of source/channel pairs, all sophisticated coding is in vain: for them, a code of block length one is sufficient to achieve optimal performance \cite{mgbrmvtrans}. Is the set of ``fortunate choices'' larger if we allow for cod ...

On optimal low-complexity source/channel coding

Martin Vetterli, Michael Christoph Gastpar, Bixio Rimoldi

Shannon's separation theorem gives a conceptually and practically appealing way to construct an optimal communication system in two independent steps, namely source compression and channel coding. However, sometimes it is worth considering {\em joint} sour ...

Multiresolution Joint Source and Channel Coding

Martin Vetterli

This chapter is a review of multiresolution source and channel coding techniques as applicable in wireless transmission. The focus is on image and video compression and transmission. Section 1 gives an introduction and a review of the separation principle ...

Image sequence coding using concepts in visual perception

Touradj Ebrahimi, Murat Kunt, Ferran Marqués

The utilization of digital image sequences is becoming increasingly important in modern imaging applications, includingHDTV, interactive video, teleconferencing, telerobotics, and medical imaging. Due to the immense amountof data in image sequences, high c ...

Approaching the Rate-Distortion Limit with Spatial Coupling, Belief propagation and Decimation

Nicolas Macris, Vahid Aref, Marc Vuffray

We investigate an encoding scheme for lossy compression of a binary symmetric source based on simple spatially coupled Low-Density Generator-Matrix codes. The degree of the check nodes is regular and the one of code-bits is Poisson distributed with an aver ...
